  The German-born Schmidt is noted for the dogged persistence by which he produced the most detailed lunar map of his day.

There he made 3,000 measurements of lunar heights, leading to publication of his 1856 ''Der Mond''. Two years later he assumed the directorship of the Athens Observatory, a position he held until his death.

The lunar crater Schmidt is named after (among others) Johann Friedrich Julius Schmidt (October 25, 1825– February 7, 1884), generally referred to as "J.F.J." or "Julius" Schmidt.

Career

The German-born Schmidt is noted for the dogged persistence by which he produced the most detailed lunar map of his day. His interest in the Moon is said to have been triggered by his encounter, at age 14, with a copy of Schröter's book. Although observing the Moon through a variety of telescope was a continuing interest throughout his life, Schmidt's main lunar work began in 1853 when he became director of a private observatory in Moravia. There he made 3,000 measurements of lunar heights, leading to publication of his 1856 Der Mond. Two years later he assumed the directorship of the Athens Observatory, a position he held until his death. In addition to his own work, Schmidt took an interest in publishing the remaining maps in Lohrmann's series from the 1820's, a project he completed in 1878, the same year the German government published his own massive map, following the same plan, but at twice the scale of Lohrmann's. Schmidt was also interested in volcanoes, earthquakes and weather.

Lunar Contributions

  • Schmidt's map is said (Dobbins and Sheehan, below) to be based on 2,731 drawings, and to record (by his own count) 32,856 craters (compared to 7,735 plotted by Beer and Mädler and 7,177 by Lohrmann). Schmidt also cataloged 348 rilles, compared to 71 for Beer and Mädler.
